1.) Neon (Ne) has 10 neutrons.
2.) Potassium's (K) atomic wieght is 39.
3.) Orbitals
4.) You take the atomic mass, and you divide by 2 (ex: an atomic mass of 12 would yield 6 neutrons!)
5.) The number of protons and nuetrons is the same (in a normal element). Since the number of protons = the atomic
number, that would mean you could find the number of electrons and protons by looking at the atomic number. (On a normal
element)
6.) Noble gases have 8 electrons in their outer ring, the number of electrons that makes ALL elements happy!
7.) Yes, this statement is true, because the protons in the nucleus have a positive charge. This charge affects the electrons in the electrons cloud. So naturally the electrons that are the farthest away from the nucleus would have more energy.
8.) The first energy level can hold two electrons. The second energy level can hold 8 electrons. The third energy level can hold 18, and lastly the fourth energy level can hold 32 electrons.
9.) Chlorine would have 18 neutrons.
10.) Chlorine would have 2 electrons in the first level, 8 in its second level and 7 in its third level.
11.) The part of the atom the weighs the most is the nucleus.
12.) The neutrons and protons are located in the nucleus.
